Module 2: Reasoning Ability
Subtopic 2.1: Verbal Reasoning (Analogies, Syllogisms, Sentence Completion)
Explanation: Verbal reasoning assesses your ability to analyze relationships between words and concepts.
Example: Question: Doctor is to Patient as Teacher is to...? (Answer: Student)
Exercises: Practice identifying analogies, evaluating syllogisms, and completing sentences based on logic.
Module 2: Reasoning Ability
Subtopic 2.1: Verbal Reasoning
Verbal Reasoning assesses your ability to analyze relationships between words and concepts. Mastering this section requires a strong understanding of vocabulary, logic, and the ability to identify patterns. Let's explore three key types of verbal reasoning questions you might encounter in the IBPS Clerk Exam:
Analogies:
Analogy questions test your understanding of relationships between words. They present a pair of words in a specific relationship, followed by a blank and several answer choices. Your task is to identify the word that shares a similar relationship with the second word in the blank as the first two words share.
Explanation: Imagine a car is to engine as a house is to what? The answer could be foundation, as both car and house rely on their respective bases for functioning.
Example: Doctor is to Patient as Teacher is to...? (Answer: Student) - Both doctor and teacher provide care or instruction to their respective counterparts.
2. Syllogisms:
Syllogisms present a logical argument with two premises (statements) and a conclusion. You need to analyze the premises and determine whether the conclusion logically follows.
Explanation: A syllogism follows a pattern: Major Premise (general statement) + Minor Premise (specific statement) = Conclusion (based on the premises).
Example:
Major Premise: All dogs are mammals.
Minor Premise: Fido is a dog.
Conclusion: Therefore, Fido is a mammal. (Valid Conclusion)
3. Sentence Completion:
Sentence completion questions provide an incomplete sentence with several answer choices. You need to choose the word that best completes the sentence logically and grammatically.
Explanation: Identify the missing piece that fits the context and maintains the overall meaning of the sentence.
Example: The runner crossed the finish line with a _____ smile. (Answer: triumphant)
Directions: Choose the answer that best completes each question.
Fast is to Slow as Up is to...? (Answer: Down)
Book is to Knowledge as Gym is to...? (Answer: Fitness)
If all birds have wings, and robins are birds, then robins must have wings. (Valid Conclusion)
The meeting was postponed because the weather was...? (Answer: terrible/inclement)
She is a _____ leader, always putting the needs of her team first. (Answer: dedicated/compassionate)
Explanation for Practice Questions:
Fast and slow are opposites, similarly, up and down are opposites.
Books provide knowledge, and gyms provide fitness.
This is a valid syllogism. The conclusion logically follows from the premises.
Terrible or inclement weather would likely cause a meeting to be postponed.
Dedicated and compassionate are both positive qualities that a leader might possess. Choose the word that best fits the context of putting the team's needs first.
Tips for Mastering Verbal Reasoning:
Build a Strong Vocabulary: Continuously expand your vocabulary by learning new words daily. Use flashcards, online resources, or read challenging material.

While the previous section covered core concepts of Verbal Reasoning, let's delve deeper with some additional examples and resources to solidify your understanding:
Advanced Verbal Reasoning Techniques:
Identifying Assumptions: Some sentence completion questions might test your ability to identify underlying assumptions. The answer choice that best completes the sentence is often the one that makes the most likely assumption based on the provided information.
Example: John refused to go outside because it might rain. (Which answer most likely completes the assumption?)
John dislikes getting wet. (Likely Assumption) (b) John forgot his umbrella. (c) John has an important meeting indoors.
Strengthening Arguments: Another strategy involves identifying the answer choice that strengthens the argument presented in the sentence completion question.
Example: Getting enough sleep is essential for maintaining good health, so children should establish a regular _____ routine. (Which answer choice strengthens the argument?)
social media (b) bedtime (Strengthens Argument for healthy sleep) (c) homework schedule
Justice is to Fairness as Peace is to...? (Answer: Harmony)
Library is to Books as Museum is to...? (Answer: Artifacts)
If no cats have feathers, and Luna is a cat, then Luna cannot have feathers. (Valid Conclusion)
The movie was a disappointment because the acting was...? (Answer: poor/unconvincing)
He is a very _____ speaker, captivating his audience with his stories. (Answer: engaging/eloquent)
Justice and fairness are related concepts, similarly, peace and harmony are related concepts.
Libraries store books, and museums store artifacts.
This is a valid syllogism. The conclusion logically follows from the premises.
Poor or unconvincing acting would likely lead to a disappointing movie experience.
Engaging and eloquent speakers capture the audience's attention.

Example: Question: In a sequence 2, 4, 8, 16, ... what is the next number? (Answer: 32)
Module 2: Reasoning Ability (Continued)
Subtopic 2.2: Non-Verbal Reasoning
Non-verbal reasoning assesses your ability to identify patterns and relationships in visual stimuli. Unlike verbal reasoning, this section relies less on vocabulary and focuses more on your visual perception and logical thinking skills. Let's explore three key types of non-verbal reasoning questions you might encounter in the IBPS Clerk Exam:
Series Completion:
Series completion questions present a sequence of numbers, shapes, letters, or symbols with a missing element. Your task is to identify the pattern in the sequence and choose the answer choice that logically completes the series.
Explanation: Look for repeating patterns in the sequence, such as addition, subtraction, alternation, or a combination of these.
Example: 2, 4, 6, 8, ... (Answer: 10) - The series follows a simple addition pattern of +2.
2. Pattern Recognition:
Pattern recognition questions involve identifying the rule or logic that governs a set of shapes, symbols, or images. You might need to identify the odd one out, complete a missing element in a matrix, or continue a growing pattern.
Explanation: Analyze the shapes or symbols based on their color, size, orientation, or any other visual characteristic that defines the pattern.
Example: Identify the image that doesn't belong in the group: (Circle, Square, Triangle, Star, Pentagon) - The answer could be "Star" as it's the only shape with more than four sides.
3. Classification:
Classification questions present a group of objects or shapes and ask you to identify the one that doesn't belong based on a specific rule or characteristic.
Explanation: Analyze the objects or shapes based on their properties like shape, size, color, or shading to identify the one that deviates from the group.
Example: Identify the letter that doesn't belong in the group: (A, B, C, E, F) - The answer could be "E" as it's the only letter that doesn't have vertical lines.
Practice Questions:
In the sequence 3, 6, 9, 12, ..., what number comes next? (Answer: 15) - The series follows a simple addition pattern of +3.
Which of the following shapes completes the pattern below? (Image shows a square followed by a circle, then a triangle) - The answer would be a square again, following an alternating pattern of square-circle-triangle.
In a group of circles, one square is present. Which object doesn't belong? (Answer: Square) - The square is the only shape that's not a circle.
What number should replace the question mark in the series 25, 20, 15, 10, ? (Answer: 5) - The series follows a subtraction pattern of -5.
A row of apples is shown, except for one object which is a banana. Which doesn't belong? (Answer: Banana) - The banana is the only fruit that's not an apple.
Tips for Mastering Non-Verbal Reasoning:
Sharpen Your Observation Skills: Pay close attention to details in the visual stimuli presented in the questions.
Practice Identifying Patterns: Regularly practice identifying patterns in everyday objects, shapes, and sequences.
Improve Your Visual Memory: Train your brain to remember the details of the visual stimuli you observe.
Time Management: Practice solving non-verbal reasoning questions quickly and efficiently, as time management is crucial in this section.
Exercises: Practice completing number or shape series, identifying patterns in images, and classifying objects based on shared characteristics.
Module 2: Reasoning Ability - Exercises

11, 14, 17, 20, ... (a) 21 (b) 22 (c) 23 (d) 24 (e) 25 Explanation: The series follows a simple addition pattern of +3. The answer is (c) 23.
55, 45, 35, 25, ... (a) 15 (b) 10 (c) 5 (d) 0 (e) -5 Explanation: The series follows a subtraction pattern of -10. The answer is (b) 10.
2, 4, 8, 16, ... (a) 20 (b) 24 (c) 32 (d) 40 (e) 48 Explanation: The series follows a doubling pattern of x2. The answer is (c) 32.
Exercise 2: Pattern Recognition (Images)
Instructions: Identify the image that doesn't belong in the group based on the visual pattern.
(Image shows a square, a circle with a dot in the center, a triangle, a circle with two dots) Explanation: The pattern might be based on the number of dots inside the circles. The answer would be the square as it doesn't have a circle with dots.
(Image shows a red apple, a green apple, a yellow apple, an orange) Explanation: The pattern might be based on color. The answer would be the orange as it's not an apple.
(Image shows a vertical line, a horizontal line, a diagonal line, a dotted line) Explanation: The pattern might be based on line type. The answer could be the dotted line as the others are solid lines.
Exercise 3: Classification
Apple, Banana, Orange, Grape, (a) Mango (b) Potato (c) Kiwi (d) Carrot (e) Cherry Explanation: The group consists of fruits. The answer is (b) Potato as it's a vegetable.
Shirt, Pants, Dress, Jeans, (a) Skirt (b) Shoes (c) Hat (d) Scarf (e) Socks Explanation: The group consists of clothing items. The answer is (b) Shoes as it's footwear, not clothing.
Wood, Metal, Plastic, Glass, (a) Rubber (b) Paper (c) Fabric (d) Leather (e) Stone Explanation: The group consists of materials. The answer is (c) Fabric as it's a textile, not a material itself.

Subtopic 2.3: Analytical Reasoning (Logical Deduction, Puzzles)
Explanation: Analytical reasoning challenges you to analyze information and draw logical conclusions.
Example: Statement 1: If it rains today, the ground is wet. Statement 2: The ground is wet. Conclusion: It rained today. (Is the conclusion valid?)
Subtopic 2.3: Analytical Reasoning
Analytical Reasoning challenges you to analyze information presented in a variety of formats and draw logical conclusions based on the given rules or statements. This section assesses your critical thinking skills, ability to identify relationships between pieces of information, and to solve problems using logic and deduction.
Concepts and Examples:
Logical Statements and Inferences:
Analytical reasoning questions often involve evaluating statements and determining whether the conclusions drawn from them are valid.
Example:
Statement 1: If it is raining, the ground is wet. Statement 2: The ground is wet. Conclusion: Therefore, it is raining. (Valid Conclusion)
In this example, the first statement establishes a cause-and-effect relationship. If it's raining (cause), then the ground will be wet (effect). Since the second statement confirms the effect (wet ground), the conclusion that it must be raining (cause) is logical.
Syllogisms in Analytical Reasoning:
While similar to syllogisms encountered in verbal reasoning, analytical reasoning syllogisms might involve more complex scenarios or multiple variables.
Example:
Statement 1: All doctors wear white coats. Statement 2: Michael is wearing a white coat.
Question: Can we conclude that Michael is a doctor? (No)
This example presents two true statements, but the conclusion doesn't necessarily follow. Just because someone wears a white coat doesn't guarantee they're a doctor (other professions might wear white coats too).
Logical Puzzles:
Analytical reasoning might involve puzzles where you need to arrange objects, assign characteristics, or solve scenarios based on a set of rules or clues.
Example:
There are three friends: Alice, Bob, and Charlie. Each has a different favorite color: red, blue, or green. Given the following clues:
Alice doesn't like red.
Bob doesn't wear green.
Question: What is Charlie's favorite color?
By analyzing the clues, we can eliminate red for Alice and green for Bob. This leaves blue for Alice and either red or green for Bob. Since Bob doesn't wear green, Charlie must have the remaining color, which is green.
Practice Questions:
Statement 1: All buses are vehicles. Statement 2: My car is a vehicle. Conclusion: Therefore, my car is a bus. (Valid/Invalid) - Answer: Invalid
If it is snowing, then the temperature is below freezing. It is snowing. Can we conclude that the temperature is below freezing? (Valid/Invalid) - Answer: Valid
There are three jackets: red, blue, and green. John wears a red jacket and Mary wears a blue jacket. What color jacket does Michael wear? (Red/Blue/Green/Cannot be determined) - Answer: Cannot be determined (without additional information)
A train is either on time or delayed. The train is not on time. Is the train delayed? (Yes/No) - Answer: Yes
In a group of people, everyone either wears glasses or doesn't. If Sarah wears glasses, can we conclude that David doesn't? (Yes/No) - Answer: No (we don't have information about David)
Additional Resources:
Online platforms with interactive analytical reasoning exercises
Logic puzzle books with varying difficulty levels
Websites with practice questions and explanations for analytical reasoning
Tips for Mastering Analytical Reasoning:

John lives on the first floor and does not wear a red shirt. Mary lives on the second floor. What floor does Michael live on, and what color shirt does he wear?
Explanation: Since John is on the first floor and doesn't wear red, he must wear either blue or green. Mary is on the second floor. This leaves the third floor and the red shirt for Michael.
Answer: Michael lives on the 3rd floor and wears a red shirt.
Fruits and Days: There are three fruits (apple, banana, orange) and three days (Monday, Wednesday, Friday). Each person has a favorite fruit and a favorite day. Sarah loves apples and dislikes Wednesdays. David hates Fridays. Who has bananas as their favorite fruit, and what is their favorite day?
Explanation: Since Sarah hates Wednesdays and loves apples, she could have apples on Monday or Friday. David hates Fridays, so he cannot have that as his favorite day. This leaves bananas and Wednesday for the remaining person.
Answer: The person who loves bananas has Wednesday as their favorite day.
Exercise 2: Analyzing Arguments
Analyze the following statements and determine whether the conclusion is valid or invalid based on the information provided.
Statement 1: All cats are mammals. Statement 2: Leo is a feline. Conclusion: Therefore, Leo is a mammal. (Valid/Invalid) - Answer: Valid
Statement 1: If it rains, the streets are wet. Statement 2: The streets are wet. Conclusion: It must be raining. (Valid/Invalid) - Answer: Invalid (it could have rained earlier)
Statement 1: Everyone in the club is a good dancer. Statement 2: Jessica is a member of the club. Conclusion: Jessica is a terrible dancer. (Valid/Invalid) - Answer: Invalid (we don't have information about Jessica's dancing skills)
Exercise 3: Identifying Valid Inferences
Read the following scenario and identify the valid inference.
Scenario: There are three departments in a company: Marketing, Sales, and Finance. Each employee works in only one department. You see Michael leaving a meeting room specifically designated for the Marketing department.
Inference: Michael works in the Marketing department. (Valid/Invalid) - Answer: Valid
Inference: Michael does not work in the Sales department. (Valid/Invalid) - Answer: Valid (we can infer he's not in the meeting because it's for Marketing)
Inference: Michael is the manager of the Marketing department. (Valid/Invalid) - Answer: Invalid (we only know he was in a meeting, not his position)
Remember: These are just a few examples. There are many variations of analytical reasoning problems you might encounter on the exam.
Tips for Effective Practice:
Set a timer: Simulate the exam environment by setting a timer when practicing these exercises.
Explain your reasoning: When solving puzzles, write down your thought process and the logic behind your answers.
Review explanations: After completing the exercises, analyze the explanations provided to understand alternative approaches and reasoning methods.
Practice identifying assumptions: Be mindful of any assumptions you might be making based on the information provided. Don't base conclusions on unstated information.
By diligently practicing these exercises and utilizing the additional resources, you'll develop your critical thinking and logical deduction skills, making you well-prepared to tackle the Analytical Reasoning section of the IBPS Clerk Exam with confidence.
Here's some additional information to enhance your understanding of Analytical Reasoning:
Advanced Analytical Reasoning Techniques:
Identifying Patterns in Puzzles: Some analytical reasoning puzzles might involve sequences or patterns. Look for repeating elements, changes in order, or exceptions to the pattern to solve them.
Example: In a line of people waiting for a bus, some wear hats and some don't. You observe the following sequence: Hat, No Hat, Hat, No Hat.
Question: What is the hat status of the fifth person in line?
Answer: No Hat. The pattern alternates between hat and no hat, so the fifth person wouldn't have a hat.
Making Inferences based on Multiple Sources: The exam might present information from different sources (text, tables, charts) that you need to combine to draw logical conclusions.
Example: A passage describes a company's departments and their employee counts. A chart shows the number of employees attending a training session.
Question: Can you determine which department has the most employees who did not attend the training?
Remember: Due to confidentiality, we cannot provide actual previous exam questions. However, by understanding these advanced techniques and practicing with various question types, you'll be better prepared for the challenges you might encounter on the IBPS Clerk Exam.

Quantitative Aptitude: Subtopic 4.1 - Number Systems
Building on the foundation of basic number systems, let's explore some additional concepts to strengthen your quantitative aptitude.
Order of Operations (PEMDAS/BODMAS):
PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right) or BODMAS (Brackets, Orders, Division and Multiplication from left to right, Addition and Subtraction from left to right) is a convention used to ensure consistent evaluation of mathematical expressions.
Example:
3 + 2 x 4 = (using PEMDAS) = 3 + 8 = 11
Solved differently without PEMDAS (incorrectly):
= 3 + (2 x 4) = 3 + 8 = 11 (although we end up with the same answer, the process violates PEMDAS)
Applications of Number Systems:
Percentages: Used in various contexts like discounts, interest rates, taxes, etc.
Ratios: Represent comparisons between two quantities. Can be expressed as a fraction, decimal, or percentage.
Example: A recipe requires 2 cups of flour and 1 cup of sugar. The ratio of flour to sugar is 2:1 (or 2/1, 200%, etc.).
Rates: Speeds, flow rates, currency exchange rates, etc. involve relating different units over time or distance.
Example: If a car travels 100 kilometers in 2 hours, the speed is 50 kilometers per hour (100 km / 2 h).
Order of Operations
Simplify 5 + 2 x (3 + 1). Answer: 13 (following PEMDAS)
Evaluate 8 ÷ (2 + 1) x 3. Answer: 6 (PEMDAS)

Algebra (Basic equations, inequalities) Explanation: Learn to solve basic algebraic equations and inequalities.
Algebra: Unveiling the Secrets of Equations and Inequalities
Algebra is a powerful tool used to represent and solve problems involving unknown quantities using variables. This section focuses on mastering the basics of solving linear equations and inequalities, which form the foundation for more advanced algebraic concepts.
Linear Equations:
A linear equation expresses a relationship between a variable (represented by a letter like x, y, etc.) and constants (numbers) using addition, subtraction, multiplication, or division. The goal is to solve for the variable that satisfies the equation.
Example:
2x + 5 = 11
Here, x is the variable, 2, 5, and 11 are constants. We need to find the value of x that makes the equation true.
Solving Linear Equations:
Isolate the variable: Use basic arithmetic operations (addition, subtraction, multiplication, division) to manipulate the equation and get the variable by itself on one side of the equal sign.
Steps to solve the above example:
Subtract 5 from both sides: 2x + 5 - 5 = 11 - 5 (maintaining equality)
Simplify: 2x = 6
Divide both sides by 2: 2x / 2 = 6 / 2
Simplify: x = 3 (This is the solution; x = 3 makes the original equation true)
2. Linear Inequalities:
An inequality expresses a non-equal relationship between a variable and constants. It can involve symbols like < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to).
Example:
3x - 2 ≤ 8
Here, x is the variable, and we need to find the values of x that satisfy the inequality.
Solving Linear Inequalities:
Similar to equations, use arithmetic operations to isolate the variable.
Pay attention to the inequality sign when manipulating it. Flipping the sign of the inequality requires reversing the direction of the inequality symbol (e.g., if you multiply both sides by -1, the < symbol becomes >).
Example (Using the same inequality):

Delving Deeper into Algebra: Exploring Applications and Advanced Concepts
We've established a foundation for solving basic linear equations and inequalities. Now, let's delve deeper into applications of algebra and explore some advanced concepts to broaden your understanding.
Applications of Algebra:
Motion: We can use linear equations to represent motion problems involving distance, speed, and time. (d = s x t, where d is distance, s is speed, and t is time)
Finance: Algebra helps calculate interest rates, loan payments, and future values based on present values.
Geometry: Algebraic expressions represent geometric shapes' perimeters, areas, and volumes.
Example (Motion):
A car travels 200 kilometers in 4 hours. What is the car's speed?
Solution:
Let s be the speed. We can use the distance formula (d = s x t) and set it equal to 200 kilometers:
200 km = s x 4 h
Divide both sides by 4 h:
s = 200 km / 4 h s = 50 km/h (The car's speed is 50 kilometers per hour)
Advanced Concepts:
Systems of Equations: Involve two or more equations with multiple variables, requiring solving for all variables simultaneously. Substitution or elimination methods can be used.
Linear Functions: Expressed as f(x) = mx + b (m is the slope, b is the y-intercept), representing linear relationships between variables.
Factoring Polynomials: Breaking down polynomial expressions into simpler forms by grouping or using specific patterns.
Example (System of Equations):

Conquering Arithmetic: Sharpening Your Number Skills
Arithmetic forms the foundation of mathematics. This section delves into essential arithmetic concepts like simplification, Least Common Multiple (LCM), Highest Common Factor (HCF), ratios, and proportions, equipping you with the skills to tackle various problems.
Simplification
Simplification involves removing unnecessary elements from a numerical expression to obtain its most basic form. This can involve:
Reducing fractions: Divide both the numerator and denominator by the greatest common factor (HCF) to get the simplest form.
Expanding parentheses: Multiply any terms within parentheses by the quantity outside the parentheses.
Combining like terms: Add or subtract terms that have the same variable raised to the same power.
Examples:
Simplify 6/12: HCF of 6 and 12 is 6. So, 6/12 = (6/6) / (12/6) = 1/2 (simplest form).
Expand 2(x + 3): 2(x + 3) = 2x + (2 x 3) = 2x + 6.
Combine 3x + 5x: 3x + 5x = (3 + 5)x = 8x.
2. Least Common Multiple (LCM)
The LCM is the smallest positive integer that is a multiple of two or more numbers. It's helpful when adding or subtracting fractions with different denominators.
Finding LCM:
List out the multiples of each number until you find a common multiple.
The LCM is the smallest common multiple identified.
Example:
Find the LCM of 4 and 6.
Multiples of 4: 4, 8, 12, 16, ... Multiples of 6: 6, 12, 18, ...
LCM = 12 (smallest common multiple)
3. Highest Common Factor (HCF)
The HCF is the largest positive integer that is a factor (divisor) of two or more numbers. It's useful in simplifying fractions.
Finding HCF:
List out the factors of each number.
The HCF is the largest factor common to both numbers.
Example:
Find the HCF of 12 and 18.
Factors of 12: 1, 2, 3, 4, 6, 12 Factors of 18: 1, 2, 3, 6, 9, 18
HCF = 6 (largest common factor)
4. Ratios & Proportions
A ratio represents a comparison between two quantities, often expressed as a fraction, decimal, or percentage. A proportion indicates that two ratios are equivalent.
Examples:
Ratio of apples to oranges in a basket: 2:3 (2 parts apples, 3 parts oranges)
A recipe requires 1 cup of flour for every 2 cups of milk (1:2 ratio, can be written as a fraction 1/2 or 0.5)
